Money, as some people think can buy everything in the world, does not mean everything.
Some people think that money which can be used to buy everything in the work means everything.
Some people think that money means everthing,which can buy everything in the world.(非限定性定语从句)。
另外,楼主的buy 后面的两个单词要显示的是不是everything 和world???
